Reported is the generation of aromatic N-heterocyclic radicals and their application in hydroamination, amidosulfenylation and bromoamination of unactivated alkenes. The resulting alkylated N-heterocyclic amines serve as important and versatile scaffolds that can be easily transformed into diverse functionalized molecules. Experimental data on the mechanism are presented.
A simple, efficient, and mild method has been developed for the synthesis of substituted 1,2,4-triazoles from hydrazines and formamide under microwave irradiation. The reaction proceeds smoothly in the absence of a catalyst and shows excellent functional-group tolerance.

di-N-heterocyclic carbene (NHC) dipalladiumcomplexes, [PdPyBr2]2(di-NHC) (2a–h), in which di-NHC represents a di-triazolylidene, featuring a 1,4-xylylene spacer between the carbene units, have been prepared from the reactions of the corresponding ditriazolium bromides with PdCl2 and excess NaBr as an additive in the presence of K2CO3 in pyridine. All of the complexes were fully characterized by NMR
